Abstract: Based on the analysis of the typical forests’ structure, the gap characters of virgin tropical montane rainforests and guided by the theory of Near Nature Forest Management, the indicators and standards of ideal structure of montane rainforest in Bawangling of Hainan Province were put forward. 7 indicators (tree stratum structure, tree species diversity in tree stratum, basic stand growing stock, volume distribution by diameter class, stand density, diameter distribution and tree species structure by merchantable timber of top class to class third ) and the standards for each of the 7 indicators were included in the ideal structure. The study on the ideal structure of montane rainforest in Bawangling Forestry Area of Hainan Province could provide a foundation for their sustainable management and also could provide an case study on the ideal structure for uneven aged forest.
